Countly CORS error

I have Countly instance installed on AWS, and i have stage and dev app both using same Countly app, in Countly i have created 2 projects for web stage and dev, i have set headers in settings as follows

Additional API HTTP Response headers: {

X-Frame-Options:deny
X-XSS-Protection:1; mode=block
Access-Control-Allow-Origin: *

}

on web staging everything seems to work fine, yet on dev i got constant CORS errors, but some request are passing with 200 status yet near 50% are failing with CORS error, can anyone point me what can be wrong?

    Hi Andrii,

    I hope you're doing well and I'm sorry for the late reply.

    After discussing your question with our development team, we believe that the root cause of the issue might be caching headers or overwriting them as they're delivered. It also explains the disappearance of the errors.
